DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 480,837, dated August16, 1892.

Application filed March 12,1892. Serial No. 424,654. (No model.)

To all whom it may concern.-

Be it known that I, GOODMAN W1Nc,a citizen of the United States,residing at Karnrar, in the county of Hamilton and State of Iowa, haveinvented certain new and useful Improvements in Four-Horse Eveners; andI do hereby declare the following to be a full,'clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form part of this specification.

The object of my invention is to improve the construction of four-horseeveners designed for use on harvesting-machines; and it consists of theseveral details of construction and combination of parts hereinafterfully set forth in the specification and more particularly pointed outin the claim.

Referring to the drawings, Figure 1 is a perspective view of my improvedfour horse evener. Fig. 2 is a top view of a slightlymodifiedconstruction, and Fig. 3 is a sectional detail View on the line X X ofFig. 2.

Similar letters of reference indicate corresponding parts in each figureof the drawings.

A indicates the pole or tongue of a har- Vester, and B a long evener-barpivoted near one end on a bolt 1), which passes through a strap orbracket 0 and the tongue A. The bracket 0 is also secured to the tongueAat c. Achain dis connected at one end to the tongue A in rear of theevener or bar B, and at its other end to the long arm of the evener B,and forms a stay to prevent the long arm from being carried too farforward when traction is made on the draft-cable. These stirrups serveas a guide to hold the draft-cable J, preferably of chain or rope ofsuitable strength, in position on the pulleys, and to keep it fromslipping off the end of the evener and falling down when it is relaxedat either end.

In Fig. 2 I have shown a slightlymodified construction of the evener-barB, in which each of its ends is mortised to form housings for thepulleys E, which are mounted on pins. The pivot bolt or pin 19, whichusually passes through the strap and pole to hold the long evener,serves the purpose of a pivot-pin for the pulley E, adjacent to the poleor tongue A.

By thus bringing this pulley directly over the tongue,with its groovededge proj ecting slightly to one side, the draft-chain from the rear endof the pole is permitted to be drawn parallel to the side of the poleand thereby enable the double eveners to be made shorter and thedraft-animals to be brought closer together. In this form of myevener-bar B, I may substitute pins (1 in the extreme ends of themortises in place of the stirrup D, as shown in Fig. 2, for the purposeof retaining the draft-cable in position on the pulleys E.

F refers to doubletrees, and G to singletrees connected by links g tothe doubletrees. A bracket H is secured to the under side of the pole ortongue A near its rear end, and a grooved pulley I is journaled inbearings in the said bracket and tongue. A draft chain or cable J passesround the pulley I, from which the two ends diverge, and after passinground the pulleys E at the ends of the evener-bar B are secured to thedoubletrees F at points midway of their length. In this construction ofmy four-horse evener the draft is on the rear pulley I, which,beingjournaled to a rigid part of the machine, will consequen tly cause thedraft to be direct upon the machine. As all the parts of the evener workloosely, there will be no side or back draft, and as the draft-chain Jcan work perfectly free around the pulley I, each horse will bear itsequal share of the weight to be drawn, whether one pair is in advance ofthe other pair or not. By having the pulley I on the under side of thepole or tongue A the draft will have a tendency to elevate the front endof the tongue and thereby take the weightfrorn the horses necks. Bypivoting the evenerbar B near one of its ends to the pole or tongue thedoubletree near the shortest end of the evener or bar will extend acrosson both sides of the tongue, and consequently one horse of the pairattached to this doubletree will be alone on one side of the pole ortongue and the other horse will be on the opposite side with the pairattached to the doubletree near the longest end of the evener or bar B.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

In a four-horse evener,a pole or tongue, an

evener-bar pivoted near one of its ends to the to each end of the chain,and two singletrees IO tongue and the other end having a stay toattached to each doubletree, substantially as limit its forwardmovement, and pulleys jourdescribed.
